Initiation, Progression and Transmission of Holmium Laser Blast Shield Failures My business partner has repeatedly told me not to assume that others know what I know – “Get the information out there, Stephen. Much that you take for granted is new and valuable to others.” It’s hard to know what these nuggets of value are. I am usually enlightened by a customer question, complaint or concern. That is the case for this blog post examining blast shield and fiber failures as an outbreak of disease. While the outbreak described progressed rapidly due to sharing reusable fibers between laser generators, small outbreaks may also...

Losses due to boiling water in surgery can be much larger than most surgeons appreciate and, in some cases these losses approach the total pulse energy, rendering laser surgery ineffective. It is important to know the variables affecting boiling losses and how to negotiate around these losses to optimize efficacy in laser lithotripsy.

FIGURE 1: Trimedyne Holmium Fiber Connector (1991 to Present) Another common termination had its genesis (for holmium laser fibers) at Trimedyne right around 1990 (U. S. Patent No. 5,179,610, Milburn, et al., Figure 1). Trimedyne’s solution is elegant; if a bit over the top for 80W. Knowing that the OmniPulse™ holmium laser presented a laser focal spot that is too large to couple to smaller fibers, and knowing that the laser focus tended to bloom and drift due to localized thermal gradients within the laser rod(s), Trimedyne’s engineers decided to capture and reroute the energy that overfilled the Fiber Aperture....

Part 4: Fiber Design Evolution -- the early days as reflected in today's products First and foremost, for differentiation among holmium laser fibers, is the issue of fiber dimensions. Frankly, I am astonished at the lack of clarity or standardization in identifying fiber sizes within this industry. Almost all “200 micron” fibers are actually much larger than 200 microns; not as egregiously large as described in some of the urological literature, where total fiber diameters are reported as opposed to the fiber core diameters used by manufacturers, but definitely misleading to the point where incredulity dominates. I’ll have more on fiber sizes in...

Before updating this entry, a reader asked a question about a statement I'd made about the flexibility of the Boston Scientific holmium fibers AccuMax™ and Flexiva™ that I answered in the updated Part 2 entry. I am leaving my answer to that question in this entry, for congruity. Pardon the redundancy. Q: ‘How do you know Boston’s AccuMax™ and Flexiva™ are stiffer than ProFlex 200 if, as you say, you’ve never seen one of Boston’s fibers?’ A: Updated answer -- we measured the glass OD of the Boston fibers and, as expected, it is 290 microns (242 microns x 1.2 CCDR).
